Research

Research is focused on various aspects of modelling and control of internal combustion engines. Cylinder pressure based methods play a central part.

Feedback control of Homogeneous Charge Compression Ignition (HCCI) combustion using cylinder pressure for feedback is a recent topic, where the control problem consists of preparing a homogeneous charge such that compression ignition takes place at the desired crank angle. Real-time heat release analysis of the cylinder pressure trace provides quantitative feedback about ignition timing.
